To @ZZ whom it may concern.-

Be it known that I, EDWARD H. PH11 Ps,of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Making Cement-Lined Pipes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specii-, cation, and represent7 in- Figure l, a view partly in elevation and partly in vertical section of a machine constructed in accordance with my invention; Fig. 2, a broken view on a large scale of the friction mechanism for sustaining the pipecarriage in its elevated or charging position. Fig. 8 is a broken sectional view on a still larger scale, showing the core, portions of the upper and lower platforms of the pipe-carriage, and a pipe in place.

My invention relates to an improvement in machines for making cement-lined pipes, the object being to produce a simple and effective machine having a large capacity for work.

Vith these ends in View my invention consists in the combination, with averticalcone, of a vertically-movable pipe-carriage located abovethe same and constructed to receive and hold a pipe which is telescoped over the cone when the carriage is lowered and means for raising the said carriage and for controlling its descent. My invention further consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.A

As herein shown, the lower end of the vertical cone Ais detachably secured by clamps A A to a large horizontal rotatable disk B, supported on an elevated frame B and having a bevel-gear C secured to thecenter of its lower face. This construction permits the cone to be changed for other cones of different size, according to the diameter and length of the pipes to be lined. The said bevel-gear C meshes into a corresponding gear D, attached to a horizontal shaftE, supported in bearings E E and carrying at its opposite end a pulley E?, over which runs a belt F, also running over a pulley F', mounted on the same shaft F2 with a drivfrom after it has been lined.

ing-pulley F 3, to which power is communicated from any convenient source. The shaft F2 is journaled in bearings G G, attached to the floor G, which, as shown, may be considered the iirst or ground floor of the building in which the machine or apparatus is located, for, as represented, the lower end of the cone and its connections are situated in a pit below the said first floor, although they may of course be located above and upon the first floor, in which case the iioor G would become the second floor of the building. I have chosen to call the partA a cone, because itis generally so called, although in fact the said part is not strictly conical, but cylindrical throughout the main portion of its length, and tapered only at its extreme upper end.

Directly above the cone is located a vertically-movable pipe -carriage composed of a rectangular lower platform, H, connected by upright rods H with a similar upper platform, H2. Corresponding points in the ends of the said platforms are recessed, as at I I, to receive upright guides I I attached to the inner faces of the heavy upright beams I2 I2,whereby provision is made for guiding the pipe-carriage as it is raised and lowered. The lower platform, H, is constructed in its center with an opening J, to be made considerably larger thanthe diameter of any cone which may be used with the apparatus. A movable interchangeable supporting-plate J located upon the said platform over the opening J therein is constructed with an opening J 2 made a very little larger than the diameter of the cone and immediately encircled at its upper end by a shallow annular recesss J 3, adapted in Size to receive and retain against lateral displacement the lower end of the pipe a to be lined. Several of these plates respectively constructed with openings and recesses corresponding to the several sizes of pipes are provided for use with the machine in which they are readily interchanged.

The upper platform, H2, is provided with a clearance-opening K larger than the opening J, before memtioned, in alignment'therewith, and designed to permit the required tipping of the upper end of the pipe inV placing it in position in the carriage and removing it there- A pipe-holder IOO K hinged to the upper face of the upper platform, H2, near one end thereof is adapted in size to cover the opening K formed therein and constructed with an opening K2 correv spouding in size to the opening J 2 with which it aligns when the holder is in its horizontal or normal position, the lower end of the said opening K2 being immediately encircled by an annular groove adapted to receive the upper end of the pipe, whereby the saine is held in position. The said pipe-holder is secured in its closed position by means of a locking device which may take any convenient form. As herein shown, it consists in an eyescrew L, carrying a nu t L and having its eye passed through the eye of an eyebolt L2, located in a recess L2 formed in the opposite end of the platform lf2, the said eye-screw being entered into a slot L4 formed in the adjacent end of the holder K to permit the nut L' to be engaged with the upper face thereof, whereby the holder is locked down in its closed position. Several of these pipe-holders respectively having openings corresponding to the several sizes of pipes are provided so as to be interchanged with each other when the cone and supporting-plate are changed to adapt the machine to line another-sized pipe. It will be understood that when the lower end of the pipe is set into the annular recess J2 in the supporting-plate J and its upper end has been entered into the annular recess K2 in the pipe-holder K it is iirmlyheld against lateral or vertical displacement.

The carriage is suspended by means of two chains M M attached to eyes formed in the upper ends of two of its rods II' and passing over pulleys M M mounted on the shaft M2, and also over idle-pulleys N, only one of which is shown, and that in Fig. 2 of the drawings. The opposite ends of the said chains are furnished with heavy weights N', (only one of them is shown,) which partly counterbalance the weight of the carriage and its load. The said shaft M2 is supported at its ends in horizontal beams or plates O, each supported at one end upon the upper ends of the upright posts l2 l2 before mentioned. One end of the shaft M2 projects beyond its support and is provided with a gear-wheel P, which meshes into a small pinion l, (see Fig. 2,) mounted upon a driving-shaft Q, also supported on the beams O O, and carrying a friction-pulley Q', a fixed pulley Q2 and a loose pulley Q2, the said fixed and loose pulleys receiving the belt from which power is communicated to the drivin g-shaft Q. A shipper R, located below the said fixed and loose pulleys and mounted for horizontal reciprocation in the frameworkof the machine, is constructed about midway of its length with a vertical opening R', which receives the short arm S of a hand-lever S', hung on a horizontal pivot S2 in position to be manually operated from the floor G2 of the building containing the machine and forming the second iloor of the said building, according to the arrangement shown herein.

y lifting the said hand-lever into the position in which it is shown by full lines in Fig. l of the drawings the shipper will be moved inwardly, so as to throw the belt onto the iixcd pulley Q2, whereby the shaft M2 is operated to lift the pipe-carriage into its elevated or charging position, in which its lower platform .is about on the level with the Hoor G', on which the pipes are located and from which they are introduced into the carriage. ily depressing the said hand-lever into the posi tion in which it is shown by broken lines in the drawings the shipper is shifted so as to throw the belt from the fixed pulley onto the loose pulley, whereby the power is cut off and the elevation of the carriage stopped. This stopping of the carriage is by preference done automatically by means of a lug T, carried upon the chain M, adjacent to the said lever, in position to engage with the same and lift it as the carriage is raised; but this lug might obviously be replaced by some other device projecting upwardly from the upper platform of the carriage in position to engage with and lift the hand-lever at the right time.

As the counterweights N N are not su fliciently heavy to in themselves sustain the carriage iu its elevated position, I employ a friction device or mechanism. to assist them therein and in controlling its descent. As herein shown, this consists of a band U encircling the friction-pulley Q and having its lower ends attached to a substantially horizon tal lever U', (sce Fig. 2,) having its inner end hung from a bracket V suspended from the lower end of one of the beams O, the opposite end of the said lever having attached to it a heavy spring V', which normally pulls the lever downward with suilicient force to place enough tension on the band U to su pport the pipe-carriage. This friction is relieved for permitting the carriage to descend by lifting the lever by hand or by means of a treadle lV, located near the floor G2 and connected by means of a chain or band lV leading over an idle-pulley )V 2 to the outer end of the said lever U. When, therefore, it is desired to allow the carriage to descend, the workman on the floor G2 either lifts the lever by hand or depresses the trcadle lV with his foot, thus lifting the lever U' against the tension of the spring V and relieving the friction of the band U upon the friction-pnlley Q. 3y means` of this friction device the pipe-carriage is thus not only supported in its charging position, but also regulated and controlled in its descent.

As herein shown, I have arranged a cement-mixer over the apparatus and in. line with the openings in the two platforms of the pipe-carriage and in the movable supportingplate and hinged pipe-holder. This mixer consists of a long upright tapering mixingchamber X having a cylindrical lower end X', which is provided with two gates Y and Y' and forms aretaining-chamber. A beater composed of a vertical shaft Z carrying lat- TOO ITO

eral beating-arms Z is located in the tapering upper portion of the mixer and rotated by a pulley Zzattached to its extreme upper end. Funnels (not shown herein) are suitably arranged for conveying cement and water into the open upper end of the said mixer. Braces Z5 secured to the uprights I2 I2 are provided for supporting the mixer in place. After the cement and water have been thoroughly mixed the upper gate, Y, is pulled out to allow the prepared cement to fall into the cylindrical lower end of the mixer in which it is supported upon the gate Y. After this the upper gate,Y, may be pushed in again and another lot of cement prepared. Then when a pipe has been placed in the pipe-carriage the lower gate, Y', is pulled out, permitting the previously-prepared cement to fall into the pipe, as indicated by a/ in Fig. 1 of the drawings. I do not limit myself, however, to the use of this device for mixing cement, although itis very convenient, for if preferred the cement may be mixed elsewhere and poured or shoveled into the upper end of the pipe by a workman standing on the upper platform or on the pipe-holder of the pipecarriage.

The pipe a (see Fig. 3) is provided at its opposite ends with cast-iron rings b and b', the points h2 and b3 whereof engage with the cone and center the pipe thereon, and thus insure uniformity in the thickness of the lining.

In using my improved apparatus an unlined pipe or shell is taken from the floor G by one or more workmen who then walk in upon the lower platform of the carriage and set the lower end of the pipe into the groove J3 in the supporting-plate J and over the upper end of the cone A. When this has been done, the pipe-holder K is lowered into its horizontal or closed position, whereby the upper end of the pipe is firmly held in place. The pipe is now partly filled with cement, either from such a mixer as shown in the drawings or in any other way. After this has been done the carriage is allowed to descend under the control of its counterweights and friction device whereby the pipe will be slowly telescoped over the cone which is being rotated and which will displace the cement from the bottom of the pipe and form and pack it into a hard lining extending throughout its length. The points b2 and b3 of the pipe-rings b and b prevent the cement from escaping, and if there is an excess of cement they crowd it back and make it pack the closer. After this has been done the hand-lever is operated to apply the power for raising the carriage, which is automatically stopped when it reaches its elevated or charging position by the means described. The pipe-holder is then unlocked and lifted and the workmen enter upon the lower platform of the carriage and carefully disengage the pipe therefrom and carry lit away and replace it by another, and so on. An apparatus or machine constructed in accordance with my invention does the work of lining pipes very rapidly and well and with the minimum of outlay for labor and repair.

I have shown and described arotating cone, but it is not necessary that the cone should rotate, although the results are perhaps more satisfactory when it does.

I am aware that a machine for making cement-lined pipes, providing for supporting the pipes in a fixed position and for longitudinally moving a cone in them, is old, and also that it has been proposed to employ a stationary cone and provide for longitudinally moving the pipes with respect to it. I do not, therefore, broadly claim a machine providing for supporting the pipes in the fixed position and longitudinally moving a cone, or a machine having a fixed cone and providing for longitudinally moving the pipes. In view of this and the suggestions of alterations and changes made elsewhere I would have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a machine for making cement-lined pipes, the combination with a vertically-arranged cone, of a vertically-movable pipecarriage located directly over the same, and having a horizontal upper platform formed with an opening, and a horizontal lower platform constructed to permit the upper end of the cone to project upward through it, a supporting-plate located upon the lower platform, adapted to support the lower end of a pipe and to receive the cone which stops the lower end of the pipe when the cement is being introduced into its upper end, a movable pipe-holder connected with the upper platform, adapted to hold the upper end of a pipe and constructed with an opening to permit the introduction of cement into the pipe after the same has been mounted in the carriage, and means applied to the carriage for raising and lowering it substantially as described.
